Discussion

Atriplex parryi occurs with greasewood, saltbush, saltgrass, and Nitrophila. The cordate-clasping, sessile leaves and spiny branches distinguish this species from its nearest congeners.

The quelite cenizo is a very distinctive, small, bushy perennial with numerous, ascending branches and tiny leaves. It is here tentatively placed adjacent to the other dioecious, herbaceous perennial, Atriplex watsonii, from which it differs in many ways (compare descriptions). Possibly its near relatives are in adjacent Mexico, which is beyond the consideration of the present paper; certainly it is one of the most distinctive of the herbaceous taxa. According to H. M. Hall and F. E. Clements (1923), the relationships of this species lie with A. watsonii, but it is more closely similar to A. elegans in the strongly compressed, nearly orbicular, and evenly dentate bracteoles. However, both A. watsonii and A. matamorensis have opposite leaves and share the feature of the pericarp being dilated around the thickened stigma bases.
